style="text-indent:25px">型材影響成品率的因素是多方面的，就擠壓生產(chǎn)而言主要有以下幾個(gè)方面：鋁鑄錠的質(zhì)量直接決定擠壓制品的成品率。模具、擠壓工具對成品率有很大影響，它們直接關(guān)系到擠壓制品的質(zhì)量，制品合格率高則成品率就高。生產(chǎn)管理中生產(chǎn)計(jì)劃下達(dá)的合理性以及生產(chǎn)報(bào)表原始數(shù)據(jù)的準(zhǔn)確性也是提高成品率的前提。各種生產(chǎn)報(bào)表的原始數(shù)據(jù)是型材擠壓前計(jì)算鑄錠長度的重要依據(jù)。擠壓工藝包括根據(jù)擠壓比選定擠壓設(shè)備、確定工藝溫度及張力矯直工藝等，每步工藝是否科學(xué)、細(xì)致、合理也對成品率影響很大。操作人員的熟練程度和責(zé)任心是提高擠壓成品率所必備的。</p><p style="text-indent:25px">民用建筑鋁鋁型材壁薄，絕大多數(shù)鋁型材的壁厚度為0.6~2mm，形狀十分復(fù)雜，且斷面變化劇烈，相關(guān)尺寸精度要求高，技術(shù)難度**多數(shù)為多高精度薄壁型材。建筑鋁型材中的空心制品比例很大，空心型材與實(shí)心型材的比例大約為1:1，而且內(nèi)腔多為異型孔，有的常常為多孔異形薄壁空心制品。一組建筑鋁材需要組裝成不同的門窗系列或其他的建筑結(jié)構(gòu)，因此配合面多，裝配尺寸多，裝飾面多。為了減少型材品種，要求型材具有通用性和互換性，這就是提高了型材的精度要求和表面品質(zhì)要求。型材可以用于工作臺、工業(yè)流水線、傳送帶。</p><div

style="text-indent:25px">隨著經(jīng)濟(jì)的發(fā)展和人民生活水平的提高，促使民用建筑鋁合金型材的品種和數(shù)量迅速增長。目前，世界各國建成了上千條民用建筑型材生產(chǎn)線，其工藝裝備、生產(chǎn)工藝和模具的設(shè)計(jì)與制造均已基本定型，具有標(biāo)準(zhǔn)化、系列化的特點(diǎn)。民用建筑型材絕大多數(shù)采用6063-T5/T6鋁合金生產(chǎn)，這是因?yàn)?063鋁合金質(zhì)輕，有良好的塑性，工藝成型性能好，表面處理性能優(yōu)良?？梢杂盟a(chǎn)出輕巧、美觀、耐用的好型材。世界上已研制出上萬種建筑鋁型材。其橫截面積范圍為0.1~100cm，外接圓直徑范圍為8~350mm，腹板厚度范圍為0.6~15mm。型材有良好的鑄造性能。成都普通型材行業(yè)</p><p
